This application is a continuation of U.S. patent application Ser. No. 15/844,993 filed Dec. 18, 2017, the content of which is incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates to athletic footwear with ankle sprain protection and, more particularly, is concerned with an athletic footwear artificial ligament device and apparatus that preserves the total range of motion of the wearer.

BACKGROUND OF THE INVENTION

Extreme or abnormal pronation with or without plantar flexion, resulting in a sprain of one or more of the ligaments of the ankle joint, is one of the most frequent injuries experienced by both professional and non-professional athletes. A traditional approach used by many to minimizing the risk of incurring a sprained ankle is through the employment of athletic tape by immobilizing the ankle. However, this process is very time consuming and must be done properly by a trained professional otherwise in order for it to work properly.

Alternatively, there are those who prefer to utilize a wearable support system (e.g. an ankle brace) that can be easily wrapped and tightened around the ankle to be selectively worn in the inside of an athletic shoe so as to immobilize the ankle joint against abnormal rotation. However, this type of approach is uncomfortable for some making it unbearable to wear during a physical activity. Although both solutions offer different approaches on how to reinforce and restrict the ankle to minimize the hyperextension of the ankle ligaments, they each suffer from similar drawbacks. For example, both the tape and ankle brace are uncomfortable, time consuming to employ, expensive and cause the loss of normal range of motion. The loss of range of motion affects agility, athletic ability, and increases the external forces imposed on other joints as they overcompensate for the force in the kinetic chain that is passed upward due to the restriction of the ankle. This is the reason why so many high ankle and knee injuries occur.

As a result additional approaches have been produced in hopes of reducing the likelihood of ankle sprain occurrences. Some approaches are disclosed in U.S. Pat. Nos. 4,922,630, 7,171,766 and U.S. Pat. Appl. Pub. No. 2014/0223775. However, all of these prior art approaches all appear to have the same residual downfall of their counterpart (i.e. they are all focused on overly restricting the normal range of motion of the ankle). Therefore, the ongoing issue of reoccurring orthopedic injuries remains.

Accordingly, there is a long felt, as of yet unmet, need for an improved athletic footwear apparatus in the art that overcomes potential deficiencies of these past approaches and addressed the problems that may still be unsolved.
